I've been fighting with my own Drake II a bit with streaking issues, but that's another post. I'm still overall happy with Toto's build quality, flush power, etc.

I manage a bunch of rental property and am in the process of buying the first of my own investment properties. I've read on here the recommendation of installing a Drake I or Eco Drake I w/o sanagloss in these rentals. That all makes sense.

However, I was curious if anyone knows anything about these 2 lower cost models: The Rowan and the Carusoe?, so seems like a really good price for a rental property. Are these as good as the Drake? Why do I not hear about these models really ever?

The Drake isn't that much more on the street price than what you're talking about on the Carusoe. I would just get the original Drake.

Edit: On the Maris parts sheet, someone has decided to call the "CE" as meaning "dual max cyclone". That's a logical mistake. The thing has 1.28 as its top number, so I guess it makes sense to add the E, but to try to rebrand "CE" as meaning something together, it makes everything else illogical. Best just to have that E denote 1.28, which, taken with the M, means that the top number is 1.28. Semantics, really. But I would ignore that notation on the parts list in favor of the explanations above.

Thanks for the abbreviation list, helps me navigate the options a little easier

Your thoughts on those models are enough for me, just thought I'd ask. The drake seems to be a good buy for ease of mind, but had to check if those other lower cost models had any particular merit for apartment use...

Did I break a rule mentioning a supplier on here? If so, I apologize, didn't mean to step on any toes.

I would suggest the Drake for a couple of reasons. First, it is reasonably priced. Just as important however, is the fact that the Drake just doesn't clog unless something nonflushable gets lodged in the trap way. As a landlord, the last thing you want is a phone call from the renter at midnight that their toilet has clogged. The Drake is about as forgiving as a toilet can be about what is flushed.

Yeah, makes sense. I don't want a crappy toilet, just didn't know anything about these 2 low priced Totos. Thought maybe they were just less popular of a style, or an older model that has been replaced so the price was lower, or something like that. If they're actually not the same quality, then I'd rather spend the money for the better one. Seems the Drake I EL where possible (I can't stand round bowls), non-sanagloss, is the way to go.

In some cases landlord (me or my client) pays water, in others tenants do, but far more often than not in these buildings landlord pays water. What would your thoughts be on the 1.6 vs the Eco 1.28 for this application?

From reading reports of people (some have both), they see little to no difference in their performance. Word has it that to gain that extra, they tweaked the refill, flapper, and bowl/tank fill balance to eliminate any wasted water. If you can get a rebate from the utility, it's probably worth the difference.

If you don't need the ADA height, I would just go with what I have: CST744E or CST744S, depending upon whether you want the 1.28gpf (E) or the 1.6gpf(S). As Jim says, if there's a rebate on the E then that's probably worth it. If not, then either the E or S would be fine.

I don't need ADA, and as far as I know, we have no rebates available, so that won't likely be a factor.

Are you saying you have both models (eco and standard?) If so, how do you feel they compare to each other? I'd pay a little more for lower water consumption, but don't want to have more problems with streaking, etc... keep tenants happy and all that...
